Find the series for a "crime Soap" quite challenging. One can not even get up 2 min from the sofa to get a drink, even if you had missed something during a follow the arguments, which would like related, stop (unless the will at all ...)
Nevertheless I have the impression that the Season 3 acts as if you wanted something artificially roll out the story. The actions and co slopes then no longer act "authentic" and a bit far-fetched.
